摘要
分析研究了锚喷支护在大变形巷道应用中存在的诸多问题 ,并针对这些问题 ,提出采用柔性金属网改善喷层的柔性 ,提高喷层的韧性与抗裂能力 ,并对金属网材料和结构进行了实验室研究和理论分析。
Some questions on application of bolting & concrete spraying support in the strata with large distortion, and aim at these questions, the flexible mesh is used to improve the flexibility of the spraying layer, and advance the tenacity and rift-proof of the spraying layer. Last, some trial study & theory analysis about mesh material and its structure are done.
